Which integrated amp with Harbeths?

I'd highly recommend a Naim Nait - either a 3R, or a better-sounding 5. Both of those have internal phono capabilities. The newer 5i does not without the use of an outboard Stageline - which does sound fantastic, by the way.
Second choice would be an Arcam integrated. Very nice.
Third would be a Rega integrated. Also nice.
As you can see, I think your Harbeths would sound best with a British Integrated - it's a match made in Heaven.
Feel free to e-mail me to discuss any of the above combos.
Cheers, Ed

Exposure 2010S or Naim 5i. Simple.

The Portal Panache is solid state, 100 wpc, but no remote.

I also have a Plinius 9200 here. Early listening impressions are not favorable, but I'll be giving it another try. I heard Harbeth and Plinius together at CES a few years back and liked it very much.

I think a reasonable amount of power is a good idea with the Harbeths. Also, I have the impression that your Ayre CDP may be happier feeding a balanced design (not sure of that, however), so maybe the Ayre integrated is something you could take a look at.

the krell.....all the BBC derivative models love a krell

If your already using the Ayre CX-7 the Ayre AX7e may be the ticket to get the most out of your CD's (used with balanced interconnects). I am using an Ayre C5xe with an Ayre AX7e in balanced mode. I'm using the integrated to power Dynaudio Special 25's (similar power requirements) and couldn't be happier. Lot's of favorable reviews, especially for the "e" evolution upgrade.

Listen and decide! I also hear great things about Lavardin integrateds but have not had a chance to listen to them.
